A program to allow a file to be read (or played) but
not changed. Viewers are often freely distributable, even
when the editor application is not. This allows you to create
files with the editor and make the viewer available to other
users to view your files, e.g. on a {web site}. Examples
include the Word and Adobe Acrobat viewers.
